using 12f629 tmr0 delay

i am trying to create a 1sec delay using the timer0 in the 12f629, by pre loading it with 131 and when it counts up it will overflow to zero so i can test the status z, after 125 counts that will be 4msec.
(131+125= 256 ,overflow to zero)

i have set the prescaler to 1/32 tmr0.
internal osc 4mhz

is this possible with this pic or not, i am used to using the 16f84

here is my asm file>>
;blink12F629.asm
;This program will blink a LED at 1hz connected to pin 7
